i 'Mom Fon BATTERY NUTS.

Application filed` May 14,

means for mounting them in connection with a plurality .oi mold members so that nuts or di'erent sizes or` types may be produced, the elements of the core being relatively interchangeable.

With the foregoing and other objects` in view, the invention consists in the novel construction and arrangement of elements de' scribed, illustrated and claimed, it being understood that modilications mayl be made within the scope'of the' claims without departing from the spirit of the invention.

ln the drawings forming part of this application Figure 1 is a View of thecomplete assembly in elevation.

Figure 2 is a View in vertical section.

Figure 3 is a plan view of the cover plate, to be provided with an opening thru which the molten metal will flow into the upper matrix. Figure 4 is a plan view of one of the matrix blocks. i

Figure 5 is a plan view of. a block to be placed intermediate ofthe matrix blocks and to which the connected cores are to be secured by means of a transversely extending screw.

`a device constituting an adapter and having a concavity proportioned to receive the lower blocks, one .of whichis retained by a transverse screw, the adapter per se being retained on the bench or other support by means of screws passing into the latter. The adapter as a whole is designated 10, the concavity or recess therein for receiving the blocks is shownyat 11, the transverse screw passing into the lower block is designated 12, and the 192e. serial No. 277,528.

other screw devices serving the purpose indicated above ,are shown at 13.

Particular emphasis is placed upon-the several blocks employed andthe relation of the two 4part core to these blocks. The upper matrix block is designated 15, the lower matrix block is shown at 16, an intermediate I block isdesignated 17 and a cover plateor block isshown at 18. The element-last named is provided with an opening 19 having a reduced lower portion if desired and the molten metal is to be poured thru this opening into the upper matrix. Cover plate 18 is manipulated-by means of a handle 2O and a handle 21 enters an Opening in the block 15 and serves to manipulate this and thedther blocks when assembled in the manner indicated.

A. plan viewof one of the matrix blocks is shown in Figure 4, and referring to the core structure it will be observedthat the upper element of the two part core, designated 24: is provided-with a recess centrally thereof into which the pin or projection 25 is intended to lit, for the purpose of obtaining proper registration betweenthe' opening 19 and the upper matrix. Element 24 is ex- -ternally threaded as indicated at 26, and the nut is 4to be produced without the rotation of any element in carrying out the operation.

The other element of the core is designated 28 and is externally threaded, being further provided with cavity 29 for receiving pin 3() carried bythe central portion of the adapter.

The screw 12 is applied after the parts have I been assembled, and serves ltoretain the series of blocks in proper position', because of the interlocking connection now to be described.

The nuts to be formed may be of different character, such as a standard battery nut and a Dodge nut, and the upper core Aincludes a plurality of lugs or ears such as 31,`spaced as shown and each provided with a transverse bore asindicatedat 32. The lower element of the two part core includes a' central lug or ear 33 provided with a transverse bore 34.

The bores 32 and 34. will register when the ears are in interlocking position, asindicated in Figure 2, and a long screw of small diameter is passed thru one side portion of the block 17 and thru the bores in the interlocked or engaged devices.

.The matrix blocks will have first been assembled 'as shown in Figure 2 so that upon connecting the elements of the core as indi#y cated, al1 of the structure below the cover 2Dparts of the core together and preventing .site portions of the core projecting fromV opposite sides of theintermediate block and into the matrix blocks,`and means for connecting the projecting elements of the core.' 2. In a device of the class described, a two part core, for molding nuts, independent devices for forming matrix blocks into which the cores extend, and devices connecting the separation Voit' the matrix blocks.

3. In a device of the class described, a two part core, for molding nuts, independent de-A vices for forming matrix blocks into which the cores extend, and means for mounting the matrix blocks. a

4. In a device, ofthe class described, a plurality ofmatrix blocks and an intermediate block, separate cores, means for connecting the cores with each other and with the inter-4 mediate block, the cores each including portions engaging and retaining the adjacent matrix block inv contact with the intermediate block. a

5. In a device of the class described, a plurality of matrix blocks and an intermediate block, separate cores, means for connecting the cores with each other and with the intermediate block, the cores each including portions engaging and retaining the adjacent matrix block in contact with the intermediate block, and a cover plate including a molten metal delivery opening adapted ItoA discharge into a matrix block directly below the cover plate. f v

In testimony whereof I aiiix my signature.
